Troubleshooting

If there is no communication, check the following:

Check the ethernet cable. Cable length must not exceed 150 ft. (45.7 m) for CAT-5E or 300 ft. (91.4 m) for CAT-6.

If the cable was manually made, check continuity across each of the wires.

If there is intermittent communication, check the following:

Check the ethernet cable. Cable length must not exceed 150 ft. (45.7 m) for CAT-5E or 300 ft. (91.4 m) for CAT-6.
